[en] A nuclear polarimeter based on the low energy analyzing power of the ⁶Li(p, ³He)α reaction has been developed and tested for proton energies below E_p = 300 keV. The polarimeter uses a ⁶LiF target evaporated on a water-cooled tantalum backing. The target is observed at backward angles by four silicon surface barrier detectors. The energy dependence of the analyzing power under 130deg for the ⁶Li(p, ³He)α reaction has been determined down to 200 keV. Spin rotation has been observed via a magnetic field incorporated in a Wien filter demonstrating that the polarimeter is operational. (orig.)
